Noisesql is yet another bot in #noisebridge which knows all about MySQL. It's used so often that it also responds to anything prefixed with ".sql". It has a database of dong urls (dongs), a database of gong urls (gongs), and a database with a copy of the 2009 California legislature's output and the state codes (capublic). Fun things to ask it to do:

There used to be a bot that looked for certain keywords and would respond with "appropriate" images, but it was kicked and the group arguing for the bot didn't exercise their do-ocratic rights and reinstate it.

Things people have tried to break the bots so far:

Flooding. The bots are ratelimited and rejoin if they are kicked by the server.

Multiline output, like "Hello, world\nquit\n". The bots only reply with the first line of the output.

Infinite loops. The bots use setrlimit and watchdog threads to cap the maximum amount of execution time per eval request.
